Lee Harvey Oswald was the sole gunman in the assassination of President John F. Kennedy, says Larry Sabato, director of the University of Virginia Center for Politics.

"I have proof that the investigation conducted by the House Select Committee on Assassinations in the 1970s that concluded that President Kennedy was probably killed by a conspiracy was simply wrong," Sabato told "The Steve Malzberg Show" on Newsmax TV.

He said the committee relied on an audio recording supposedly made by a police officer in the JFK motorcade in Dallas on Nov. 22, 1963, in which four shots are heard, pointing to the idea of more than one gunman.

"We brought together the best audio experts in the world and we have clearly disproven it," Sabato, author of the new book, "The Kennedy Half-Century: The Presidency, Assassination, and Lasting Legacy of John F. Kennedy," published by Bloomsbury USA.

"None of them were gunshots. It turns out that the policeman who had the stuck microphone on his motorcycle, who was recording the sound, was not in Dealey Plaza as the House Select Committee had insisted but rather was 2.5 miles away from Kennedy at the time the shots were fired.

"There's no way the sounds could have been recorded. This thing is primitive. This microphone on the motorcycle is equivalent to a telephone receiver."

Sabato said the "overwhelming evidence" proves Oswald was the sole shooter.

But, he added, 'We will never be able to say with 100 percent certainty that Lee Harvey Oswald acted completely alone."
